Disposable syringe device auxiliary unit for preventing iatrogenic infection through needle

Abstract

A disposable syringe device auxiliary unit of the present invention for preventing iatrogenic infection through a needle includes a cap holding section for disposing and holding therein a cap which covers, when a medical treatment is performed, a needle positioned at the extreme end of a syringe barrel constituting a disposable syringe device; and a needle separating section for separating the needle, which is covered with the cap and fitted on an end of the syringe barrel, therefrom.

Description

This application claims benefit of Japanese Application No. 2001-189973 filed on Jun. 22, 2001, the contents of which are incorporated by this reference.BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a disposable syringe device auxiliary unit for enabling a cap to be attached to a needle or enabling the needle to be removed from a disposable syringe device with one hand.2. Description of the Related ArtRecently, disposable syringe devices that are discarded when they are used once, that is, so-called disposable syringe devices are widely used to prevent iatrogenic infection through syringe devices. The disposable syringe device is composed of a sterilized disposable syringe and a sterilized needle mounted thereon. The needle is covered with a sterilized cap.Therefore, when chemicals are injected into or blood is collected from a patient using the disposable syringe device, the cap is detached, and the exposed needle is stuck under or in the skin...

AI Technical Summary

Benefits of technology

An object of the present invention is to provide a disposable syringe device auxiliary unit for preventing a cap, which is detached from a disposable syringe device just before it is used, from being lost.

Another object of the present invention is to provide a disposable syringe device auxiliary unit for enabling a cap to be reliably and easily attached again to the needle of a disposable syringe device after the device is used while preventing a hand and a finger from being stuck with the needle by mistake.

Still another object of the present invention is to provide a disposable syringe device auxiliary unit for preventing the hand and finger of a medical practician from being stuck with the needle of a disposable syringe device by mistake when he or she separates the needle from a syringe barrel.

To describe briefly, the disposable syringe device auxiliary unit of the present invention includes a cap holding section, in which a cap covering a needle positioned at the extreme end of a syringe barrel constituting a disposable syringe device, is disposed and held in a medical treatment; and a needle separating section for separating the needle, which is covered with the cap and fitted on an end of the syringe barrel, therefrom. With this arrangement, it can be prevented to lose the cap covering the needle as well as the occurrence of a medical disaster caused by an accidental needle stick can be prevented because the cap is attached to the needle and the needle is separated from the syringe barrel with one hand.

Problems solved by technology

Therefore, when chemicals are injected into or blood is collected from a patient using the disposable syringe device, the cap is detached, and the exposed needle is stuck under or in the skin, in the muscle or in the blood pipe of the patient.

One of the most serious problems in medical disasters, which happen to doctors, nurses, and medical practicians in a medical site, is a so-called accidental needle stick in which a used needle is stuck in a hand or a finger of them.

In addition to the above, however, there is also a possibility that the accidental needle stick happens when a cap is attached to the needle again.

Further, in an operation in which a disposable syringe device may be used repeatedly, there is a possibility that the accidental needle stick happens when a disposable syringe device used once is left with the needle thereof exposed because a cap is lost or when a needle is repeatedly separated from and mounted on again a syringe barrel to draw chemicals into the syringe barrel.

Further, the accidental needle stick also happens when a person comes in touch with a needle without a cap by mistake when used disposable syringe devices are discarded as medical wastes, and when needles are discarded in the state that they are separated from syringe barrels.
